Title: Dust collector
Inventor: FURUYA MASAYASU
IPC: B03C3/15
Filed: 1980-09-02
Abstract: PURPOSE:To capture soot and dust of extra fine particles with high dust correction rates by acting kinetic vector and electrostatic force to be exerted to the soot and dust in waste gases simultaneously in the same direction. CONSTITUTION:The waste gas contg. soot and dust produced by the combustion flows through a waste gas lead-in pipe 14 from the direction tangential to the cylindrical part 11 of a cyclone separator 1, where it swirles at high speed. On the other hand, the high voltage electrode 2 connected to a high voltage power source performs corona electric discharge as shown by dotted arrows toward the dust collecting electrode 5 on the inside surface of the separator 1 grounded from an electric discharge part 3. The soot and dust particles receive centrifugal force by the swirling motion, collide against the inside surface of the separator 1, are decelerated of kinetic energy and fall into a capturing chamber 13. On the other hand, the particles swirling at high velocities in the corona discharge area are electrostically charged simultaneously and quickly. The combined force added with centrifugal force and electrostatic force acts in the radial direction of the separator 1, and the soot and  dust of extra fine particles are also captured at high dust correction rates from the  waste gaseous flow which is discharged at high speed.

Title: Controlling method of minority carrier diffusion length
Inventor: TAKAGI JIYUNKOU
IPC: H01L21/322
Filed: 1977-10-12
Abstract: PURPOSE: To reduce minority carrier diffusion length by making positive use of recombination centers generated by ion radiation damages.  
     CONSTITUTION: The distribution of recombination centers is considered primary- approximately identical in shape to the energy distribution released as a result of impingement with atom nuclei by ion implantation. The defect distribution when light atom ions are implanted increases from the substrate surface toward the inside, becomes meximum at the portion RD slightly shallower than the projection range RP of primary incident ions, and thereafter sharply decreases. Hence, the distribution of the recombination centers immediate after the implantion in analogous to the defect distribution, wherein the maniority carrier diffusion length becomes shortest at RD, thence increases to become of the value at the time unimplanted time. When annealing is done, annihilation progresses from the portions where defects are small and ends at RD. Hence, the recombination centers are left only at RD by making conditions optimum, whereby only the diffusion length of the minority carriers there may be shortened
